Image-to-video prompting: camera motion without identity drift

Motion prompts are not image prompts

The image already defines appearance. Re-describing every visual detail can invite the video model to reinterpret the frame. Focus on continuity, camera behavior, subject action, environmental motion, and prohibited changes.

A compact motion prompt structure

A useful prompt can be short when each instruction has a clear job.

• Frame lock: preserve the uploaded image as the exact first frame.
• Subject lock: keep identity, product, body, vehicle, or wardrobe stable.
• Camera: dolly, slider, orbit, crane, handheld, or locked tripod.
• Action: one readable movement with realistic speed and weight.
• Secondary motion: light, fabric, hair, reflections, smoke, or water.
• Prohibitions: no morphing, duplicate objects, new text, or camera shake.

Edit around model limits

Not every shot needs complex action. Controlled detail shots, slow pushes, and short inserts often create a more expensive sequence than forcing one generation to perform an entire scene.
